Fig. 2 is a cross-section of the same in any suitable manner. This lathing 14 is and showing the girder construction, the lathoffset from the bottom of the beams A suffiing and concrete being shown partially re ciently to provide for a filling of concrete or 5 45 moved from the floor for the purpose of illussimilar plastic material applied from above tration. Fig. 3 is a section looking to the left and of the desired depth for fireprooiing the from line 3 of Fig. 2 with the concrete rebottoms of the beams. As shown at the left moved. Fig. 4 is a perspective detail of the in Fig. l, the space above this lathing 14 is ceiling-hanger shown in Figs. 1 to 3. Fig. 5 completely filled with plastic material; but I00 50 isaperspective detail of the rod-hanger shown at the right in Fig. 1 is shown a construction in Fig. 2 in connection with the girder firein which an air-space isformed beneath the flange of the beam by applying a second piece of metallic lathing 15 about the flange of the beam and offsetting it below the beam, according to the air-space desired, by offsetting pieces 2, which are shown as angular pieces of sheet metal, although it will be understood that any suitable means may be used for this purpose, the concrete below the beams then filling the space between the two pieces of lathing ll 15 and forming an air-space inside the lathing 15 below the beam-flange.

After the rods 12 and lathing or other reticulated metal 13 14 have been placed in position, as shown in Fig. 1, a filling of concrete or similar plastic material (J is applied from above, filling all the space above the metal 13, embedding the rods 12 and the webs and flanges of the beams, and setting through the openings in the reticulated metal, so as to secure the desired anchorage therein, this concrete also being packed down through the spaces between the rods 12, from which the reticulated metal 13 has been removed near the flanges of the beams, so as to fill the spaces inside the metal 14, and thus form an integral body of concrete or similar plastic material, filling the space between the beams and around the webs of the beams and forming a body of fireproofing below the flanges of the beams, either without an air-space below the flange of the beam, as shown at the left in Fig. 1, or with an airspace, as shown at the right in Fig. 1. This floor construction of concrete or similar plastic material preferably extends level with the tops of the beams A, as shown in Fig. 1, and upon it the flooring D may be applied directly, but is preferably supported thereon by wooden or other joists E, as shown. This floor construction is complete in itself and maybe used with beams supported in any suitable manner or with girders and girder protection of any desired form. In girder constructions, however, I preferably protect the girders throughout by a body of concrete or similar plastic material continuous with the flooring-concrete O and extend this body of concrete or similar plastic material also below the bottoms of the grinders, so as to provide a fireproof protection below the girders. In this construction the wire lathing or other reticulated metal 13 does not extend to the end of the beams A, but terminates at a distance from the girders B, according to the thickness of girder-fireproofing desired, and upon the rods 12, adjacent to and on opposite sides of the girder B, are hung hooked rods 16, which extend downward below the flange of the girder sufficiently to provide the desired thickness of fireproofing material below the girder-flange, and to these rods 16 and to horizontal rods 17 is secured wire lathing or other reticulated metal 18,within which the filling of concrete orsimilar plastic material G is packed for fireproofing the girders.

As shown, the girder B extends above the beams A, and the concrete 0 is extended upward immediately about the girder to the top of the latter, so as to fireproof the web and under side of the flange of the latter, the flooring D then resting upon the top of the girder and upon joists E, which are supported on the general body of the concrete, which extends only to the top of the beams A. The horizontal rods 17, below the girder B, are preferably supported and held in position not only by the rods 16, depending from rods 13, but also by hangers attached to the flange of the girder. The hanger used for this purpose and shown in Fig. 2 and in detail in Fig. 5 consists of a flat piece of metal a, which is split from each end through a portion of its length and a portion of each end turned up to form flanges 3, embracing the flange of the girder B and the other portions of the ends turned down and bent to form depending hooks 4, which receive and support the rods 1'7, asimple, cheap, and efficient clip or hanger for supporting rods from the flanges of beams being thus provided.

The construction of fireproof floor and girder'protection thus far described is complete in itself and may be used without a ceiling or with a plaster finish applied directly to the under side of the lathing 13 14 18, so that the floor and ceiling construction is integral, the concrete or similar plastic material projecting through the openings in this lathin g or other reticulated metal forming an efficient base for the plaster, or a ceiling of any suitable form suspended below the beams A may be used. I have illustrated in the accompanying drawings, however, a combined floor and ceiling construction which embodies certain features of the invention, and this form of suspended ceiling and the concrete floor is preferably used. In this construction the ceiling is suspended from the bottom flanges of the beams A by hangers b, which are preferably of the form shown in Figs. 1 to 3 and in detail in Fig. 4, these hangers being formed of a piece of flat metal which is cut inward near one end to form a hook 5 and then slit, so as to form an arm 6 of the length desired, the length of the piece of metal I) and of this arm 6 depending on the distance at which the ceiling is to be placed below the bottom flange, and the other slit portion extending along arm 6 is bent upward and over and the end of the strip 1) similarly bent over to form hooks '7, embracing the bottom flange of the beam A, the arm 6, with hook 5, then depending below the flange of the beam and below the fireproofing under the beam previously described to support the ceiling at the desired distance below the beam and fireproofing. The hooks 5 of these hangers I) receive the ceiling-supporting bars 19, which are shown as flat bars, but which may be of any other suitable form, and by these bars 19 is supported the ceiling, which is shown as formed of wire lathing 20, secured to the bars by wire ties S at suitable intervals and on the under side of which ,lathing is applied the ceiling-plaster or similar plastic material F. lt-will be understood, however, that any'other form of reticulated metal may be used and secured to the ceiling-supportinglbars 19 in any suitable manner.

The form of the hangers b for supporting secure the same result or the form of the hanger and part out or punched therefrom be Varied widely. It will be understood also that the length of the depending portion of the hanger will depend upon the distance thatit is desired to suspend the ceiling below the beam and beam protection, and the form and construction of the hanger may be modified accordingly.

In Fig. 6 I have shown a hanger in which the clip portion for securing the hanger to the beam-flange is punched from the body of the hanger b, one end of the strip outside this punched portion being bent away from the body of the hanger which forms the depending ceiling-supporting arm 6, so that the punched-out portion lies along the under side of the beam-flange and the upper end of the hanger and the free end of the punched-out portion so turned over to form the hooks 7 overlapping the beam-flange. The depending arm 6 inthisconstruction is shown as given a quartentwist, so as to brin git flatwise against the side of the ceiling-supporting bar 19, and then bent up to form the hook 5, on which the bar 19 rests.

In Fig. 7 l have shown another construction similar to those shown in Figs. 4 to 6, except that the parts are formed by cutting the strip in a somewhat-different manner and so as to form the hook 5 with a notch 9, which re ceives the flat bar 19 and holds it firmly in position.

\Vhile I preferably use my improved floor construction with a suspended ceiling, as shown, these two parts of the construction forming a combined floor and ceilingconstruction of the preferred form and embodying certain features of the invention, it will be understood that this floor and suspended ceiling may be used independently of each other in any suitable construction. It will be understood also that many modifications may be made in the construction shown by those skilled in the art without departing from the invention.
